SIGNORS TO BRITISH COMPANY.

To all whom it may concern.'

Be it knownthat KENNETH Aran and GEORGE WILLIAM WORTLEY, subjects of theKing of Great Britain, residing at Falkirk, Scotland, have inventedcertain new and useful yImprovements in Gas Heaters, of which thefollowing is a specication.

This invention relates togas heaters and consists in detail Improvementsin various parts thereof, the main object being the supply of a boilingburner and trivet to the plate of a gas heater, and the improvementsfurther consist in the provision of an injector burner and kettlesupports which are all accurately lined up with respect to each other.Separate and independent control is given to both the fire and boilingburner, and a loose plate is provided which effectually conceals themechanism when the boiling burner is not in use and a guard isA providedto prevent damage to the radiants when the boiling burner is in use.

The entire fittings of the trivet are interchangeable, the same p-lateserving either a plain fire or one with a boiling burner and to converta plain fire to aV boiling burner it is only necessary to connect aneXtra cock to the injector, fX the boiling burner by one screw to thefuel plate and drop lthe boiling burnerffender into position. f

The invention will be clearly understood from the following descriptionaided by the annexed drawings in which- Figure 1 is a front view of partof a gas heater with the loose plate in position.

Figure 2 is a similar view with the loose plate removed and burner.

Figure 3 is a similar view with the loose pla-te, trivet and trivetfront removed and showing the boiling burner.

Figure 4 is a plan of the trivet and showing the trivet front in dottedlines. y

Figure 14 is a section on the line e e of Figure 13.

Figure 15 is a fragmentary view ofthe pot support.

Figure 16 is a longitudinal section of the burner.

Fligure 17 is a plan of the burner. Figure 18 is an end viewof theburner. Figure 19 is a view of the guard. Figure 2O is a front elevationbroken and showing section of guard rail.

Figure 21 is a part sectional plan of the guardV rail. y j The gasboiling burner 1 (Figures 16 and 17) is preferably of the slit varietyand has `a' lug 2 projecting `from one sidev thereof,

which lug extends under a lug 3* projecting forwardly from the frontedge of. the plate 3, preferably midway'between the ends of the'latter'(Figs. 7 and .8), and is secured to `said lug 3a in any suitable manner,as by a boltinserted through an Iaperture in the lug 2 and an aperture 4in the lug 3a, the other or inlet end 6-'of the boiling burner 1 beingslipped over the injector 7. i

The injector and taps Figures 10, ll'and 12 are of the dual varietyleading from one source of supply at 8 and the' plugs 9, l0 are eachoperated separately to control its particular burner.' As will be seenfrom Figure 12the plug casings are in twocastings `11, 12 screwed.together and then screwedforbolted tothe lug-which projects forwardlyfrom the plate 3 (Figure 3) so that the injector ends 7 and 13 arepositioned in the mixing chambers of the burners in correct alignment,the injector end 13 being in the burner 5 and the injector end 7 at theboiling burner 1.

The trivet table 14 Figures 2, 4, 5 and 6 is made to fit over the plate3 and is supported adjacent its forward edge by a vertically arranged'plate 15, the whole forming a complete fender which fits the front ofthe heater, the trivet table 14 having a flange 17 on its under sideadjacent its rear edge which flange is adapted, when the trivet table isin place, to seat between a longitudinal Harige 16 on the plate 3 adia-`cent the forward edge of the latter and a,

4engages with a lip pair-of -studslS projecting upwardly from they plateS'orwardly of the depression 16, and thus be held firmly andin properposition with .regard to the burner.

The centre of the trivet table 14 is provided with an opening 1'9constructed to carry a ring plate (Figures 13 and 14) having radial arms21 forming supports tor the kettle or the like and this ring plate 2()is provided with a hooked lugQZ `which 23 on the trivet table y and vata diametrically Opposite portion of Y table by a the boiling burner isnot required, the trivet -A -tableiand ring plate are covered by a looseplate or cover *'27, as shown in Figure l,

Yto give Vthe stove an ordinary appearance.

We employ a rod 28 shaped at the ends VV'to engage the side edges 29 ofthe back brick or frame 30 and provided with two pivote/d or fixedhooked rods 31, 31 which are hooked `on to the cross rod 32 which holdthe radiants 38 in place. The rod "28, the hooked rods 3l and cross rod32 form an efficient guard against the Vradiante 33 being injured by thekettle or other device when being placed upon or removed from above theboiling ring.

That we do claim as our invention, ,and desire toV secure by LettersPatent is l. In a gas heater, a plate, radiants supported bythe plate, aburner below and in iront o-said radiante, a trivettable in front "ofsaid'radiants over said burner and having a flange on its'under side,said trivet table having an aperture-centered over said burner', studson the plate for engagement with the flange on said trivettable to holdLgas to .said burner,

of combustion-can passjector means secured to said table in properrelationV to the burner, a lug projecting lforwardly from said plate andto which said burner is secured,injector means secured to the plate forsupplying a vertically arranged plate connected to and supporting thetrivet table adjacent its forward edge, a kettle support in the aperturein the trivet table, a plate 'tor covering the trivet table, andra guardfor the radiants comprising vertically and horizontally connecting bars.Y

Q.. In a gas heater, a plate, radiants supportedbj7 'the plate, a burnerV in -ront of and belowthe torwardedge of said plate, a

Vtrivet table in front of said radiants having an apertureV cent-eredover said burner and provided with a flange Vonrits underside the platehaving studsprojecting from its upper side for engagement with saidflange Y to hold the trivet table in proper relation 'to' the burner, aklug projecting from the' plate to which said burner is secured, Vintheplate for supplying gas to said burners, said .trivetV table beingconnected adjacent its forward edge to a vertically placed plate, akettle support in aperture, and a plate for covering the trivet. Y Y

In a gas heater, a plate, radiants supported by said plate, a burner infront-ot and'below Vthe :torward'edge of said plate, a trivet table infront oflsaidradiants having an aperture centered, over said burner anda Harige on its underside, studs on the plate for engagement Vwith theflange of the trivet table to hold the latter in proper relation to theburner, and a lug vprojecting from the plate to which said'burnercured.

In testimony whereof we have hereunto set our hands in presence'ot` -twosubscribing witnesses. j i i 'i KENNETH AIRD.l Y GEORGE WILLIAM WORTLEY.
